For me it is a daily problem. The problem is working on products designed 2-3 years ago where customer wants to add more features.


However on newer designs it is less of problem as that you can specify a large processor. The justification for large costs is the hours it saves in software development which is valid for most projects except really high volumes ones.

Hello everyone,


I am wondering about the space optimizations in avr-gcc. How many of you have had problems fitting your code into the device that you are working on, and what do you normally do? Is it a large enough problem that you have had to hack your source code, or turn on compiler optimizations, or do linker tricks?


I was wondering because I am interested in studying the effect of different optimization passes in avr-gcc on the code size of the program.


Have any of you had this problem, and how many of have had code size issues?
